CROSS REFERENCE TO RELATED APPLICATIONS

The present application claims priority to U.S. Patent Provisional Application No. 62/827,654, filed Apr. 1, 2019, the contents of which are hereby incorporated in their entirety.

TECHNICAL FIELD

The present disclosure generally relates to an apparatus for controlling camera operations, and more particularly to a control system and method for single-handed seamless camera control.

BACKGROUND

In broadcast, it is common use to have a single control panel per camera that controls all functions available in a camera and its connected elements, such as a camera lens. In the industry, the person operating such a panel is referred to as a “shader” and his or her primary responsibility is to modify the parameters of a camera in such a way that the image is pleasant to watch and/or matches a reference camera.

A typical control panel consists of a varying number of buttons, a display and a so-called stick. The stick is a control element, typically located at the lower end of the panel, sticking out perpendicularly to the control panel's surface. It can pivot up and down, controlling a function. In addition, there's a second control in the stick, which is a ring rotating around the stick, controlling a second function.

With conventional designs, existing camera control panels feature a stick with only two operational controls: generally the lens' iris control and master-black control. However, when making a transition, for example from indoor to outdoor scenes, more than two controls need to be operated simultaneously in order to present a pleasing scene for a viewer. Normally this is performed using two hands: one hand controls the stick while the other hand controls another control element on the panel. As a result, conventional configurations limit the amount of cameras that can be shaded simultaneously to one, while often multiple cameras require shading at the same time. Further, this is an ergonomically disadvantaged way of operating, resulting in transitions that are not as smooth as they could be.

DETAILED DESCRIPTION

Various aspects of the disclosure are now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to promote a thorough understanding of one or more aspects of the disclosure. It may be evident in some or all instances, however, that any aspects described below can be practiced without adopting the specific design details described below. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate description of one or more aspects. The following presents a simplified summary of one or more aspects of the disclosure in order to provide a basic understanding thereof.

When a camera moves from capturing an indoor scene to capturing an outdoor scene (as an example transition that may occur in filming and image capture), a number of properties typically change, including, for example, the intensity of the scene, and the color temperature of the scene and the contrast in the scene, although those of ordinary skill in the art will recognize that many other ambient properties may change. The elements that are needed to manage the changes for purposes of clear and pleasant video capture (from the viewer's perspective) include the lens' iris and the color-balance. In some exemplary aspects, the apparatus described herein is configured to allow the shader simultaneous controls of the lens' iris, master gain, color-balance and master-black (black levels). With the apparatus provided, all controls may be assigned to elements on the stick so that smooth scene transitions can be realized with a single hand, while the camera can remain on-air. In addition, the shader may be transitioning a second camera similarly using his or her other hand, if needed.

The example described above is only one example of operation; many different scenarios can benefit from the streamlined control of the apparatus. Every production may require other critical elements that need to be controlled simultaneously and smoothly. Therefore, the functions assigned to the control elements can be chosen freely and modified freely. Going forward, the variety of functions that need simultaneous control is only growing, further increasing the possibilities of usage of the apparatus. New video-modes, such as High Dynamic Range (HDR) video, may require different and new functions than used in conventional and existing camera control. The apparatus overcomes the disadvantages and limits of typical control panels, and helps prevent control panels from becoming even less user-friendly than they are today with such existing cumbersome configurations. When control panels were initially contemplated, most camera control functions were not continuous functions with a resolution well within visible steps, but were coarse steps. As a result, the need for smooth controls and the functions themselves did not exist, or they were not typically available when a scene was visible to the viewers (‘on-air’).

FIG. 1 illustrates an apparatus 100 for single-handed seamless camera control, in accordance with an exemplary embodiment. In an exemplary aspect, the apparatus 100 (i.e., a single-handed seamless camera controller) has various control components that are configured to aid a shader in modifying scene and camera parameters, making scene transitions smooth and seamless and avoiding jarring visual changes for the viewers. In this embodiment, the apparatus 100 comprises a stick 110 extending from a base mounted on a panel 114, a first ring 112 disposed at the base region 140 of the stick 110, a second ring 108 disposed around a bottom portion in the control region 120 of the apparatus 100 and a third ring 104 disposed around a top portion in the control region 120 of the apparatus 100. The apparatus 100 further comprises a dividing element 102 (i.e., a first control region divider), a dividing element 106 (i.e., a second control region divider) and a button control 116.

According to one embodiment, the stick 110 is configured to move forward and backwards, or laterally side to side, though other two-way directional configurations are also contemplated. In essence, the stick 110 is generally assigned to a function that does not need fine or continuous adjustment.

According to this embodiment, the first ring 112, the second ring 108 and the third ring 104 of the apparatus 100 are implemented as rotary controls that are continuously rotatable. The continuous rings are designed so that the first ring (i.e., the lower ring) 112 can be easily controlled while a shader's hand rests around the stick 110 for precision modifications. The second ring 108 and the third ring 104 at the top of the apparatus 100 are implemented such that they are easily controlled by the shader's fingers. In exemplary aspects, the second ring 108 and the third ring 104 are separated from each other according to a pre-calibrated distance ensuring they can be distinctly and independently controlled. Further, the length of the stick 110 may be adjustable to conform to the size of a shader's hands. As described above, the ring controls are “continuous” controls, as opposed to toggle switches, in order to provide smooth operation as required by the shader. In some embodiments, there may be more than three rings for different controllable aspects. In some aspects, the apparatus 100 may provide physical or digital/mechanical audio feedback as each ring control is rotated. In some aspects, each ring may provide different feedback so a shader need not look directly at the control, but can aurally determine which control is being adjusted.

Further, the present disclosure also contemplates that instead of rings, pressure sensitive control elements may be used to change each mapped setting. The pressure sensitive control elements may change the value of particular parameters, such as master gain, master black or the like as a user pushes harder or releases pressure on the control element. In some embodiments, the control elements may be touch sensitive “digital” rotary control elements that modify the values of mapped functions based on movement detected on the touch sensitive digital rotary control element. In other embodiments or aspects, any form of pressure sensitivity or movement could be used as control elements, where the elements can be activated without needing to look at the control. In exemplary aspects, sensory feedback is provided that can be felt by the shader.

In some aspects, the adjustments to each control element correspond to seamless changes in the mapped function. For example, the gain changes in steps of 0.1 Db and movement of a ring to control the gain would produce a seamless change for the viewer. However, the resolution (e.g., step value), sensitivity and the positioning of each ring may be adjusted according to user desire, either through a user interface or other configuration method.

In a specific configuration example, the stick 110 can be configured to be mapped to control a camera's lens' iris (e.g., a lens iris controller), while the first ring 112 controls master gain (e.g., a master gain controller), the second ring 108 controls color-balance (e.g., a color-balance controller) and the third ring 104 controls master-black values of the camera (e.g., a master-black value controller). Thus, if the shader wants to adjust the master gain, the shader rotates the first ring 112 with his or her fingers to increase or decrease the mast gain based on the direction of rotation (e.g., clockwise versus counterclockwise). Upon rotation, the adjustment of the ring control 112 transmits a signal (i.e., a master gain control signal) to a camera under the shader's control to increase or decrease the master gain, depending on the direction of rotation of the first ring 112. According to a predefined user configuration, as the value of the master gain reaches a minimum (i.e., a minimum gain control threshold) within the defined range, the master gain may no longer be reduced despite continuous rotation of the first ring 112. Similarly, as the value of the master gain reaches a maximum (i.e., a maximum gain control threshold) within the defined range, the master gain may no longer be increased despite continuous rotation of the first ring 112.

However, it is possible that a user may desire that a control value loop back around from minimum to maximum (or from the maximum value to the minimum value) as the control is rotated one or the other direction continuously and the apparatus 100 can be configured accordingly. In one embodiment, a user may desire that the continuous control of the first ring 112 be linearly mapped to the master gain control where turning the control a specified degree only changes the master gain control by a specified value. In another embodiment, the rotation may be non-linearly mapped to the master gain control. For example, as a shader rotates the first ring 112, the master gain increases logarithmically, exponentially, or in any other predefined proportion, of which such control can be configured according to user control or predefined settings, for example. Similarly, each of the continuous controls may be configured as described above regarding loop back, continuous rotation, linear and non-linear value mappings and the like.

In addition to the physical layout of apparatus 100, the implementation is such that the function controlled by all control elements can be assigned by a user in order to support the described operations, as well as any other set of functions such as HDR settings (e.g., gamma breaking point, where the gamma curve of the two parts can be set independently to create an artistic look within the large exposure range), or even new functions that are yet to be developed. Thus, according to an exemplary aspect, the apparatus 100 is fully programmable according to a user's need and any of the controls can be mapped to any of the functions provided by a camera under control. An exemplary embodiment for configuring the apparatus 100 will be described in more detail below.

In an exemplary aspect as further shown in FIG. 1, element 102 and element 106 are configured as mechanical dividers to ensure that controls 104 and 106 can be rotated independently and will not be inadvertently adjusted by a user during operation. Moreover, the button control 116 is enabled when it is pressed down and can be configured, for example, to enable a display controlled by the shader to switch to a particular camera for transitioning. In some aspects, the apparatus 100 can be configured to set a reference value for a particular parameter. For example, if the shader has adjusted the first ring 112 to a point where the master gain is ideal for a particular scene, and later the shader needs to change the master gain, the shader may store the current master gain value and subsequently recall the stored master gain when returning to the particular scene instead of adjusting the first ring 112 to attempt to redundantly find the ideal settings, using additional control elements on the apparatus 100. In some embodiments, the apparatus 100 transmits a transitioning signal to the camera so the camera transitions from the current master gain to the stored master gain using an additional control element on the apparatus 100. Similarly, the controls for storing and retrieving master gain values may also or alternatively be used to store other camera and scene settings for easy retrieval and application. In other embodiments, artificial intelligence may be used to monitor changes that a shader makes based on historical transitions performed by the shader, given particular parameters. So when a scene transition with similar parameter transitions are encountered, a controller associated with the apparatus can be configured to learn and predict the functions' settings and apply them automatically, or assist the shader in providing suggested values or the like. In one exemplary aspect, a shader can configure how much predictive adjustments are made and balanced with how much manual control the shader has.

As an example, an image capture setting controller coupled to the apparatus is configured to preset reference values for the respective parameters controlled by the first, second and third continuous control elements. During operation, the image capture setting controller can determine characteristics of the video content (e.g., the scene) captured by the camera, such as lighting, shadows, color, movement and the like. Using one or more of these detected values, the image capture setting controller can then identify the preset reference values for the respective parameter based on the determined characteristics to assist the shader in suggested values. In one aspect, the image capture setting controller automatically changes the settings of the apparatus 100 based on the detected characteristics of the captured video content to optimize further video capture.

Currently, when cameras goes outdoors, shaders must change the amount of light, as well as color temperature which takes a significant amount of time. The image will look bluish, normal, overexposed or underexposed for example, for a period of time and a viewer will likely notice the irregularity. Apparatus 100 however greatly reduces this time because a shader can control critical parameters for this transition with one hand. Thus, gain and color temperature can be adjusted simultaneously at the same time that there is a scene transition.

It should be appreciated that an exemplary design for apparatus 100 is shown in FIG. 1. Alternative configurations may have different ergonomic considerations or control placements, but the inclusion of at least two continuous controls will be preferable.

FIG. 2 illustrates a panel 200 incorporating the apparatus 100 for single-handed seamless camera control, in accordance with an exemplary embodiment.

Specifically, in an exemplary aspect, each shader controls a plurality of panels similar to panel 200, where each panel 200 controls a camera as shown in FIG. 3. Each panel 200 incorporates the apparatus 100 as a control element among a plurality of other control elements 204 and 206. The panel 200 can also include a display panel 202 that is configured to display, in one aspect, one or more settings being currently adjusted, the value of the settings as they are adjusted, other settings that may be affected, in addition to default values that are selected to be continuously displayed as the shader adjusts the various control elements. According to one aspect, the panel 200 may also come equipped with multiple apparatuses 100, each apparatus 10 controlling a single camera, or controlling different functions of the same camera.

FIG. 3 illustrates a control system for exemplary operation of multiple panels in controlling multiple cameras, in accordance with an exemplary embodiment.

In an exemplary embodiment, a shader 300 may be operating a panel 330 with apparatus 332 in order to control camera 302 and a panel 340 with apparatus 342 in order to control camera 304. In some aspects, the panels 330 and 340 are directly coupled to the respective cameras 302 and 304 wired or wirelessly, respectively, but in other aspects the panels 200 may control the respective cameras 302 and 304 wirelessly, or wired, via a network 301.

In one example, the camera 304 can be configured to transition from capturing an outdoor scene 310 to an indoor scene 320, where the values of the camera parameters drastically differ to achieve similar picture quality. As the camera transitions from scene 310 to scene 320, the shader 300 operates panel 340 and adjusts, for example, iris lens, master gain, and the like using apparatus 342, which corresponds to apparatus 100 as described above with respect to FIG. 1, for example. Simultaneously, however, the camera 302 can also be configured to automatically transition, for example from a first scene (e.g., an indoor scene) to a second scene (e.g., an outdoor scene). Since the shader only needs a single hand to control multiple parameters of a single camera, the shader can control the parameters of camera 302 by manipulating the apparatus 332 of panel 330, simultaneously while he or she adjusts the parameters of camera 304 by manipulating the apparatus 342 of panel 340. Further, the shader 300 may adjust the parameters according to a reference camera 303. In some embodiments, the shader generally control more than two cameras, and may control up to eight to eleven cameras. However, with the present configuration, shaders may control two cameras at once instead of previously known configurations where only one camera could be controlled at one time.

In exemplary aspects, the apparatus 332 and 342 each have an associated controller (e.g., an image capture setting controller) that maps values from the controls to video and camera controls. For example, apparatus 332 has a controller 350 that determines which control was actuated. In one aspect, the controller 350 can be integrated as a component of apparatus 342. In another aspect, controller 350 can be a separate component wired or wireless coupled (e.g., by Bluetooth connection) to apparatus 342. In either case, controller 350 can be a computer processing device configured to execute software for performing the algorithms and functionality described herein. For example, the controller (e.g., an image capture setting controller) can be configured to automatically access preset content capture settings for the one or more cameras and adjust the control elements (and/or provide recommendations for the operator) based on the detected characteristics of the content currently being captured by the one or more cameras.

In an exemplary aspect, once the controller 350 knows which control was activated, the controller 350 can be configured to query (i.e., by sending a video parameter request) a controls database 360 to determine which video parameter that the activated control is associated with. In some aspects, the controls database 360 may also include range mappings, methods of mapping the controls, and the like as described with respect to FIG. 1. The controller 350 is configured to dynamically retrieve the associated video parameter (alternatively referred to as function), and the method of mapping from the control to the range of the video parameter. The controller 350 maps the control value to the video parameter value, and then dynamically transmits the mapped value to the camera 304, or whichever camera is coupled to a particular panel. Similarly, in this aspect all panels and apparatus map their controls using a similar controller. In some exemplary embodiments, each panel contains a controller for the apparatus 100 as described above. In some embodiments, each panel may store some or all of the information contained in the controls database 360 to avoid latency over the network when performing camera controls, in order to ensure seamless scene transitions.

Moreover, in one aspect, the controller 350 can be configured to record pre-set settings, as selected by the operator of apparatus 340, for a particular scene with particular image capture settings for one or more over cameras 302-304. In an further example, apparatus 340 and/or controller 350 can provide a user interface that enables the operator to define the pre-set settings by name so that the operator can subsequently and dynamically recall these settings (e.g., by sending a video parameter request) to control database 360.

In some exemplary aspects, a panel (e.g., panel 330) may be coupled to an HDR camera 302, but then the panel is configured to couple to an SDR camera, or vice versa. The panel 330 and the apparatus 332 each have adaptable configurations where a controller recognizes the change and remaps the control values of each control element on the panel 332 and the apparatus 332 according to the change.

FIG. 4 is a flow diagram of a method 400 for single-handed seamless camera control, in accordance with exemplary aspects of the present disclosure.

The method 400 begins at step 402 when a shader initiates operation of the apparatus 100, for example, and proceeds to step 404.

At step 404, a controller of the apparatus 100 detects movement of a continuous control on the apparatus 100. For example, the controller may detect movement in one of the ring controls (e.g., first ring control element 112, second ring control element 108 and third ring control element 104), or any actuator on the apparatus 100. In some aspects, the controller also detects control actuation for any control element on an associated panel (e.g., panel 200).

At step 406, the controller retrieves a video control that is mapped to the adjusted continuous control. Because each of the control elements is configurable to change any number of settings or functions, the controller may need to reference the most current mapping for each control element from a database, a local record in local memory or the like.

At step 408, the controller maps the value of the continuous control to a respective value in a range of values of the video control. Each control element (e.g., the rotary ring elements) have an associated “step” change (e.g., 1 dB for gain or the like), thus the controller must assess the measured adjustment of the control element, retrieve step information, and then use this information to map the adjustment into a permissible range of the particular control.

Finally at 410, the controller applies the mapped value to a preselected parameter of an associated camera associated with the video control. In other words, whatever function is assigned to the particular control element that has been adjusted, the controller takes the mapped value and adjusts the function according to the mapped value. This may occur over a network or may be directly controlled or the like. The method terminates at 420. Moreover, it should be appreciated that steps 404 to 410 can be repeated as part of a feedback loop as the shader is using the apparatus 100 during video content capture.
